CABLE TAKE-Ur.v

To all/whom t-mag/ concern:

Be it known that lViLniAM C.. F. ZiniiiaimAN, a citizen of the United' States, residing at Lon-e rlree, in the county of Johnson and State of Iowa, have invented? certain neuY and useful Improvements in Cable rFake-Ups; and vdo herebydec'lare the following tobe a full, cleaigand exact description of the invention, such as willi yenable others vskilled iii the art to which it apperta-ins to make and use thesanie.

This invention relates to-v improvements in cable take-ups, and particularly to devices of thischaracter provided Vwithl a earn cable grip, such, for instance, as indicated' in my prior Patent No. 615,945, dated "Dec 13, 189e. y

Although thestructure illustrated in said patent has proved very efficient, certain diificulties in its use have manifestedthemselyes one of which is the tendency toward-intein' lference between the yloose ends of the cable and the crossingftautportion of the cable, no particular provision being'inade for' locating the loose Vend out of the path of theuta'ut portion-with the result that some times inv practice the crossing` portions ofthecable are injured and some tinies-thellan-ge of the pulley is spreadl or broken. Another difficulty some times arising in the use of thev said patented take-up is a tendency on the part of the taut portion of the cable to slip below the main plate of the takevup, and a still further objection arises from the use ofthe return lap of the short cable,'because of the-incident waste of cable. i

Theobjects of the several features ofimprovenient are toeffectively overcome these difficulties as will in part be hereinafter pointed out and in part become apparent.

In the accompanying drawing,- Figurel is a plan view of'y a 'take-upembodying the featuresvof the present invention. y

Fig. 2is a. front view thereof.

Referring to the drawingcbynuinerals, 1 indicates the main plate-which is vstrengthened by appropriate ribs or flanges'2, 2, at its under face, and is provided with a transverse, arcuate flange `3 upstandi'ng from its upper face. the flange 3 being strengthened by lateral flanges or ribs 4, 4.

A downwardly opening- 'hook 5 outstandslaterally -f-roml andisdisposed* above disposed atv one: end of theplate Vand extend ing fromy one edge thereof, while the' cable Y guidingaiid retaining vlug 7' is formed inplate 1 and preferably f formed integral therewith, thehook 5 being 1Y0 beinoi disposed withfits end portion eX- tending through theborek8, the cable being of a dianieterhfillling'thebore except at the: enlarged .portion 9,. whereat thel strands of thecable are spread` apart' and crinipedandf interlille'd with babbitt 'oi' other appropriate material, as indicated at 131. fllheopposite end of the hitchin cable :11'01is connectedtos a cable hook 1&2 cation of the cable.

The .inajoii portion ofthe upper faceof' plate 1 is flat and smooth., and? an eccentric disk or cam :1:3' rests ilatwi'se thereon, ay studi 14;-upstand'ing'-froml the upperface of plate- 1 landk forming a' bearing fory disk cani 13, said' disk caniibeing formedwithan aperture surroundingl said stud 'and disposed eccentric to the circleid'escriltedbythe periphery ofthe disk, so'l .thatithe disk acts asa cam in revolvingon the-,stud y:14k-as a pivot. A cross pin .-15 eXtends th-i-ouglistndi 14 above cain 13 so as. to obviate the possibility of accidental dislocationl of the cam. lThe Vface oif'flange 3 next the cani 13 .is

yjacent thelange 3.whenxthe.cam .isa'fin its' The Ibranch ...groove `17 gripping position. is formed by the provision of an eXtra wide flan-ge 18 vextending Vfroim cam 13 and serv-v ing" to confine the loose end of the draft Vcable 19 to sustain the same out of con-- apteditoy facili-tate appli# tact with the taut portion of the cable. Branch 17 leads spirally from the groove 1G so that the cable 19 naturally accommodates itself to the position given it in said grooves incident to a wrapping of the cable about the cam.

ln operation, when it is desired to hitch some intermediate point of draft cable 19 to an object, as for instance, a stump to be pulled, it is not necessary to wind in the full length of draft cable, but instead, an embodinient of the present invention is applied to the desired point of the draft cable by merely swinging the earn 13 on its pivot outwardly to the position indicated in dotted lines in Fig. 1, ceiling a single coil of the cable 19 about the cam with the loose end extending along the branch groove 17 while the main portion of the coil lies in the groove 16, and the draft cable extending through hook 5, and then swinging the cam into the clamping position seen in Fig. 1. lt will, of course, be obvious that the loose end of the cable extending out of groove 17,

while shown in the drawing only as a stub for the savingof space, may in fact be a hundred feet long or of any other length, according to how much of the draft cable has been paid out, and the relative location of the point of application of the cam hitch. lNhen the cam hitch has thus been applied to the draft cable, the hitch cable 10 may be applied appropriately to the object to be drawn. To detach the hitch cable to the draft cable, it is only necessary to relax the stress on the draft cable, swinging disk earn 13 to the dotted line position of Fi 1, and recoil the draft cable from the cani. Gbviously, flange 3 may be any appropriate stop or shoulder cooperating with cani 13 to clamp the cable. Retaining Aug 7, in practice, effectively prevents accidental slipping of the draft cable below the plate or body 1.

@wing to the extraordinarily heavy strain to which the parte are subjected, the flange 3 and cam 13 are so disposed with relation to each other as to obviate the possibility of the cam swinging to a position suciently be- .1 fond the dead center line to wedge between its pivot 111 and the flange 3. In fact, the position of these parts is such that the cable will be gripped only while under pressure, that is while the pulling cable is subjected to strain and when this strain is relieved the cam v13 is free to swing laterally to the dotted line position for enabling` removal of the take-up fromthe cable 19. rlhus any such disastrous results as would follow wedging of the cam against the cable while the cable is disposed between the cam and flange 3 are avoided.

Copies of this patent may he obtained.. for

lllhile l hai-fe illustrated but a single cable l0 it is ap eurent, of course, that the plate 1k may be providel with a cluster of such cables in any appropriate number, such as would enable the connection of the pulling cable 19 to a plurality of stumps at one time. The multiple number of cables 10 would, of course, be varied according to conditions and could all be secured in the bore 8 or when preferred the plate 1 could be provided with a number of bores 8 corresponding to the number of cables 10 of the cluster.

W hat l claim is 1. ln a cable take-up, the combination of a body plate provided at one side with spaced apart longitudinally extending integral reinforcing ribs and having on its opposite side near one end a transversely extending stop flange curved inwardly at one end and provided with outstandingintegral reinforcing flanges at its outer side merging into the body plate, said body plate being,` provided near one lateral edge with a longitudinally extending cable receiving socket enlarged at one end to receive the unraveled extremity of a cable to bind the latter in the socket, and a disk eccentrically mounted upon the said flat opposite side of the body plate and adapted to swing into engagement with the curved end of said stop. flange to bind between the disk and the flange cable wound upon'the periphery of the dislr, said dislr having a grooved projection at one side thereof into which the cable is adapted to be trained to prevent overlapping of the cable on the disk.

2. ,in a cable take-up, the combination of a body plate provided with a flat side and a stop dange rising from one end of the plate at said side, and a disk eccentrieally pivot-ed to the. body plate against said flat side and provided with a peripheral'groove adapted to receive a cable therein, said dislr having a projection upon its side opposite from the plate, and thev projection having a groove therein leaning obliquely from the peripheral groove' of the disk to receive a portion of the cable wound upon the disk, said projection and groove therein being located at a point diametrically opposite to the eccentrically pivoted point of the disk to prevent overlapping of the cable wound upon the disk.

ln testimony whereof l affix my signature in presence of two witnesses.
